Skinny woman and heavier guy sex?!

I wasn't sure if I wanted to ask this because it embarrasses me a little but I'm also so curious to know.

I am a very skinny petite body kind of woman and all my life I've dated guys who are in shape. After being single for 6 years I decided to get back out there. Lately it's heavier guys who've caught my attention. I personally think they can be sweeter sometimes and there's so many other great qualities of a heavier guy but I have a feeling a lot of times woman will reject them because they're not fit etc. I've been open to getting to know a few BUT I've been so curious to know how sex would be. I'm afraid it wont be as pleasant or maybe it will be painful or I don't know. But I have so many thoughts in my mind about it and I would really like to know how sex was for you if you dated a heavier guy or currently are and you're like me skinny petite body.

Edit: I'm 5'5 around 110lbs

And I'm guessing he's around 300lbs and I know he's 6'1
